Pentax k100d long exposure?

Could anyone help me changing the setting on my Pentax k100d so i can produce a photo with long exposure.
I've looked in the manuel and havnt found anything that tells me specifically what to do.

I really want to take a photo with a trail of lights.

You should try to choose the mode Tv to be able to set a long exposure time. If you need to expose longer, try mode B.

Manual mode ("M" on the dial) will let you go to 30 seconds. Bulb mode ("B" on the dial) lets you take longer shots in which you hold the shutter button down as long as you want the shutter to stay open (and the battery lasts).

if you want to do timed exposures longer than 30s, say for star trails, you can get a cable release with a timer built in, like this one on amazon

I should point out that I haven't used this exact model, but I have used others like it with success.

The idea is that you set the camera to B and let the cable release timer handle the exposure time. You don't get any metering, but for star trails you would probably be figuring exposure out yourself anyway.
